Using the built-in single-photon avalanche diode (SPAD) array of LiDAR to obtain random numbers has become an efficient QRNG solution. However, the current QRNG method only utilizes the temporal ...

Due to the lack of objectivity of electron microscope focusing in traditional manual focusing, resulting in inaccurate image focusing, this paper proposes a high-precision focusing method for electron ...

Three-dimensional (3D) imaging is essential for investigating cellular structure and dynamics. Traditional optical methods ...
